NJ Weekend March 12-13: Pi, Pirates, Penguins & St. Patrick's

This weekend, feast on some pi. And no, I didn't forget the 'e'. Princeton is celebrating Einstein's birthday with a Pi party (and there actually will be 'pie' there) and pi-rates are cavorting on Pirate Adventure Day. And if you can stand any more alliteration, there's also a Proper Pets workshop at Turtle Back, a penguin spa at Jenkinson's Aquarium, and of course, more St. Patrick's fun. There's other good stuff too, but none of it starts with 'p', so you'll have to keep reading. Have fun!

3.14 is Albert Einstein's birthday and Princeton is going all out to celebrate the genius and the number pi. The Historical Society of Princeton is throwing a Children's birthday celebration and showing some of Einstein's own personal belongings. There will also be a pie eating contest for kids ages 4 and up, a pie throwing event, an Einstein look-a-like contest, a kids pi recitation contest for kids 7 and up, a family Geek Freak No-Socks Sock Hop at the YWCA with root beer floats and under the sock limbo, an interactive science fair at the Princeton Public Library suitable for all ages, a dinky train ride with Einstein, and plenty of things to buy in Princeton for just $3.14.
